Latch assembly for joining two conduits

ABSTRACT

A latch assembly for connection of conduit, the assembly comprising a female portion and a male portion, wherein each of the female portion and the male portion have a shell and a connection device. The connection device of the female portion includes a connection assembly with a molded-in slot, a release button, and a raised rib or alternatively is a connection opening. The connection device of the male portion includes a cantilevered region with a ramped engagement feature or alternatively is a raised cantilevered release button. When connected the cantilevered region or button deflects to accommodate the female portion until the ramped engagement feature or button engages the molded-in slot or connection opening, thus releasing the deflection. Depressing the release button disengages the latch allowing separation of the assembly.

FIELD OF THE INVENTION

The present invention relates to a coupling device. More particularly,the present invention relates to a coupling device for conduits. Evenmore particularly, the present invention relates to a releasablylatching coupling device for fluid conduits.

BACKGROUND

The use of conduits is well known for transporting fluids in the form ofliquids or gases to and from various locations. Conduits can also beused for transporting solids of various forms. It is also well knownthat splices are often necessary within a given length of conduit forextending the length of the conduit, providing for redirection of aconduit, providing connections to supply reservoirs or distributiondevices, or other known reasons.

In light of the many uses of conduits and the known need for splicingconduits, several devices exist for assisting the splicing of a conduit.For example, a garden hose splice involves a threaded male end and athreaded female end that may be used to splice more than one garden hosetogether. A similar connection may be used at the connection of the hoseto a water spout at one end and to a water distribution device such as asprinkler or nozzle at the other end. As an additional example, rubbertubing may often be spliced or connected to equipment through the use ofa hose barb.

In the medical industry, conduits are often used to transport fluids inthe form of liquids or gases from reservoirs to patients, fromreservoirs to equipment, between equipment, or otherwise. Also, splicesin these conduits are frequently connected, unconnected, and rearrangedas patients are transported, equipment is moved, and procedures areconducted. Existing threaded connections often require attention toassure the threads are aligned and can also be time consuming to screwtogether. Practitioners need to be efficient and sometimes need to actquickly in an emergency. Thus, these connections need to be made in asimple motion and in a timely fashion. Patient safety requires thatthese connections remain secure in an environment where the conduit maybe pulled on, tripped over, or otherwise treated so as to inadvertentlyundue a splice or a connection. Finally, patient safety also requiresthat the connection provides for uninterrupted flow of the transportedmaterial through the connection.

There is a need in the art for a conduit coupling device that canprovide for splicing or otherwise connecting a conduit in an efficient,secure, and effective manner.

Components may also beconnected by welding, fusing, pressing, or melting, if appropriate, andappropriate liquid and/or water tight seals or sealing devices may beused. Unless specifically otherwise disclosed or taught, materials formaking the present invention and/or components thereof may be selectedfrom appropriate materials such as plastics, metals, composite materialsand the like, and appropriate manufacturing or production methodsincluding those known to ones skilled in the art may be used.

The present invention may be more completely understood with referenceto the Figures, which are described below.

FIGS. 1-4 show a latch assembly 100 according to certain embodiments. Inone embodiment, the latch assembly includes a female portion 120 and amale portion 140, which latch together forming a seam 170. Shown inphantom on FIG. 1 are two conduits 160 and 180 associated with thefemale portion 120 and male portion 140 respectively. The conduits showninclude a proximal end 161, 181 with a hose barb 162, 182. While in oneembodiment, hose barbs 162, 182 may be provided for joining the proximalends 161, 181 to polymer tubing, in other embodiments, the proximal ends161, 181 may be provided with other joining features, such as threads,flanges, couplings, clamps, etc.

Referring to FIG. 3, the conduits are again shown in phantom and eachhave a distal end 163, 183. The conduits are shown in matingrelationship where the distal end 163 associated with the female portion120 is a female distal end and the distal end 183 associated with themale portion 140 is a male distal end. Those skilled in the art willunderstand and appreciate that the distal end 163 could instead be amale distal end and the distal end 183 could instead be a female distalend.

The remaining disclosure relates to several embodiments of the latchassembly and does not discuss the conduit specifically. It is intendedthat each of the embodiments may include a conduit associated with themale portion of the latch assembly and a conduit associated with afemale portion of the latch assembly. The connection between the twoconduits, apart from the latch assembly connection, may be a male/femaleconnection as discussed above, a flanged connection or some other typeof abutting connection, or any type of conduit connection known in theart. In addition, a gasket or other sealing means known in the art maybe incorporated at the conduit connection to prevent leaking or otherescape of matter from the conduits at the connection.

The present disclosure is intended to include any type of conduitincluding, but not limited to, tubing, piping, ducting, or other canaltype devices for use in transporting matter.

It is further intended that the conduit may be connected to or otherwiserestrained by the associated portion of the latch assembly in some form.The relationship between the conduit and the latch assembly may be afixed connection, a sleeved connection, or any other connection known inthe art. Additionally, the conduit may be a molded portion of theassembly. Finally, features of the latch assembly may include devices orstructures associated with assisting the connection of the includedconduits. For example, opposing annular rings may be included on eachmale/female portion of the latch assembly for passing through of aflanged conduit, such that, when assembled, the opposing annular ringson each portion of the assembly would compress the respective flanges ofthe conduit together providing a sealing force. Other devices orstructures for assisting with the conduit connection and sealing knownin the art are also included.

FIGS. 5-8 show the female portion 120 of the embodiment shown in FIGS.1-4 in greater detail. In this embodiment, the female portion 120 of thelatch assembly 100 is shown to have a proximal end 121 and a distal end122. The female portion 120 is also shown to include a shell 125 and aconnection assembly 135.

In the present embodiment, the shell 125 of the female portion 120 has alongitudinal axis 123. The shell 125 is generally hollow with a varyingoblong shaped cross-section when viewed along the longitudinal axis 123.The cross-section varies from relatively narrow at its proximal end 121to relatively broad at its distal end 122. The shell 125 includes anexit opening/connection for a conduit at the proximal end 121. The shell125 further includes an abutment face 129 at the distal end 122, theabutment face 129 following the perimeter contour of the shell 125.Those skilled in the art will understand and appreciate that virtuallyany shaped cross-section may be used including, but not limited to,circular, square, and rectangular shapes.

In the present embodiment, the connection assembly 135 of the femaleportion 120, as best shown in FIGS. 7 and 8, comprises a release button137, a molded-in slot 136, and a raised rib 138. It is noted that thefemale portion 120 includes two connection assemblies 135 located onopposing surfaces of the female portion 120. For purpose of description,only one of the connection assemblies 135 is described herein.

In this embodiment, the release button 137 comprises a section of theshell 125 and thus matches the contour of the shell 125, but isseparated from the shell 125 by a molded-in slot 136 and a raise rib138. The release button further has a proximal end 131 and a distal end132, where the proximal end 131 is near the proximal end 121 of thefemale portion 120 and the distal end 132 is near the distal end 122 ofthe female portion 120.

In this embodiment, the release button 137 is surrounded by themolded-in slot 136 on three sides and part of a fourth side. Regardingthe first three sides, two are generally parallel to the longitudinalaxis 123 and the third side is along the release button's distal end132. The fourth side, where the molded-in slot 136 only partiallysurrounds the release button 137, is along the release button's proximalend 131. The molded-in slot 136 creates a peninsula-like shaped releasebutton 137 in a cantilevered condition where the release button 137increases in width as it extends from the proximal end 131 to the distalend 132. The cantilevered condition allows the distal end 132 of therelease button 137 to flex into the interior space of the female portion120 when pressed on from the outer side.

In contrast to the molded-in slot 136, the raised rib 138 is shown tocompletely surround the release button 137. The raised rib 138 projectsoutwardly relative to the inner space of the female portion 120 and hasa side face 139 defining the outer perimeter of the molded-in slot 136.

FIGS. 9-12 show the male portion 140 of the embodiment shown in FIGS.1-4 in greater detail. The male portion 140 of the latch assembly 100 isshown to have a proximal end 141 and a distal end 142. The male portion140 is also shown to include a shell 145 and a connection assembly 155.

In the present embodiment, the shell 145 has a longitudinal axis 143.The shell 145 is generally hollow with a varying oblong shapedcross-section when viewed along the longitudinal axis 143. The outercontour of the shell 145 at its distal end matches the outer contour ofthe shell 125 at its distal end 122. This provides for a smooth surfacetransition between the female 120 and male 140 portions of the latchassembly 100. The cross-section of the shell 145 varies from relativelynarrow at its proximal end 141 to relatively broad at its distal end andincludes an opening/connection for a conduit at its proximal end 141.Those skilled in the art will understand and appreciate that virtuallyany shaped cross-section can be used including, but not limited tocircular, square, and rectangular shapes. Those skilled in the art willalso understand and appreciate that a smooth transition may not alwaysbe necessary or desired and thus the outer contour of the shell 125 andthe shell 145 would not need to match.

In the present embodiment, the connection assembly 155 of the maleportion 140 is situated at the distal end 142 of the male portion 140and is separated from the shell 145 by an abutment face 149. Theconnection assembly 155 comprises a necked-down section of the shell145. The outer contour of the connection assembly 155 substantiallymatches the inner contour of the shell 125 of the female portion 120 atits distal end 122. This provides for a mating relationship between thefemale portion 120 and the male portion 140 where the connectionassembly 155 extends within the shell 125.

In this embodiment, the connection assembly 155 further comprises acantilevered region 157, a molded-in slot 156, and a ramped engagementfeature 158. It is noted that the connection assembly 155 includes twocantilevered regions 157 located on opposing surfaces of the connectionassembly 155. For purposes of description, only one of the cantileveredregions 157 is described herein.

In the present embodiment, the cantilevered region 157 is a section ofthe connection assembly 155 and thus has the same contoured shape as theconnection assembly 155, but is separated from the connection assembly155 by a molded-in slot 156. The cantilevered region 157 has a proximalend 151 and a distal end 152, where the proximal end is nearer to theproximal end 141 of the male portion 140, but still remains within theconnection assembly 155. The distal end 152 is near the distal end 142of the male portion 140.

The molded-in slot 156 surrounds the cantilevered region 157 on threesides creating the cantilevered condition and causing the cantileveredregion 157 to have a peninsula-like shape, which is wider at its distalend 152 than at its proximal end 151. The molded-in slot 156 surroundsthe cantilevered region 157 along its proximal end 151 and along twosides generally oriented parallel to the longitudinal axis 143.

At the proximal end 151 of the cantilevered region 157, a rampedengagement feature 158 is shown. As best shown in FIGS. 10 and 11, theramped engagement feature 158 slopes outwardly, relative to the innervolume of the male portion 140 as it extends toward the proximal end 151of the cantilevered region 157. Thus, when an object, resistant todeflection, slides along the surface of the cantilevered portion 157from its distal end 152 to its proximal end 151, the object willencounter the ramped engagement feature 158. As the object continues toslide along the cantilevered region 157, the object will interact withthe sloping surface of the ramped engagement feature 158 causing theproximal end 151 of the cantilevered region 157 to flex into the innervolume of the male portion 140.

As best shown in FIG. 11, a latching face 159 of the ramped engagementfeature 158 is provided and is defined as the vertical face beyond theend of the ramped portion of the ramped engagement feature 158. Thelatching face 159 is shown opposing the abutment face 149 and separatedfrom the abutment face 149 by a portion of the connection assembly 155and the molded-in slot 156. The ramped portion of the ramped engagementfeature 158 and the latching face 159 come together at a point or ridge158A.

In the present embodiment, the width of the ridge 158A, measuredperpendicular to the longitudinal axis 143, is shorter than the portionof the molded-in slot 136 along the distal end 132 of the release button137 of the female portion 120. This is so the ridge 158A of the rampedengagement feature 138 can penetrate the molded-in slot 136 when themale portion 140 and female portion 120 are connected, as will beexplained in more detail below.

Having described the female portion 120 and the male portion 140 ingreat detail, reference is again made to FIGS. 1-4 showing the latchassembly 100. The female portion 120 and the male portion 140 may beconnected together in mating relationship. When the two portions areconnected, the abutment face 129 of the female portion abuts against theabutment face 149 of the male portion creating a seam 170 and preventingthe two portions 120 and 140 from advancing any further toward oneanother.

Reference is now made particularly to FIG. 3 for describing in greaterdetail the latching nature of the connection between the female portion120 and the male portion 140. As the distal ends 122 and 142 of the twoportions 120 and 140 are brought together in opposing fashion, theconnection assembly 155 of the male portion 140 is inserted into thefemale portion 120. As this occurs, the inner surface of the shell 125passes along the surface of the connection assembly 155 and thus passesalong the surface of the cantilevered region 157 and eventuallyencounters the ramped engagement feature 158. As the two portions 120and 140 continue to be advanced toward each other, the interaction ofthe inner surface of the shell 125 with the ramped engagement feature158, causes the proximal end 151 of the cantilevered region 157 todeflect into the inner volume of the male portion 140. It is noted thatthe portion of the shell 125 between the molded-in slot 136 and thedistal end 122 is minimal providing only a narrow strip of material topress against the ramped engagement feature. However this strip isreinforced by the raised rib 138 and also can rely to a certain extendon the tensile hoop stresses developed in the shell as the two portionsare assembled. As the two portions continue to advance toward eachother, the cantilevered region 157 deflects sufficiently for the ridge158A of the ramped engagement feature 158 to clear the inner surface ofthe shell 125, thus allowing for complete advancement of the femaleportion 120 and male portion 140 toward one another and bringingabutment face 129 into contact with abutment face 149 preventing furtheradvancement. At the same time, the ramped engagement feature 158 passeswithin the volume defined by the shell 125 and encounters the molded-inslot 136. The ridge 158A of the ramped engagement feature 158 enters themolded-in slot 136 allowing the cantilevered region 157 to spring backinto its non-deflected position. As this occurs, the latching face 159of the ramped engagement feature 158 is brought into abuttingrelationship with the side face 139 of the raised rib 138 creating alatched condition in which the two portions 120 and 140 are releasablyconnected.

To release the female and male portions 120, 140 the release button 137may be pressed. In so doing, as can be seen in FIG. 3, the releasebutton 137 engages the ramped engagement feature 158 and the distal endsof both the release button 137 of the female portion 120 and thecantilevered region 157 of the male portion 140 deflect into the innervolume of their associated shells. When the release button is pressedwith sufficient force, the cantilevered region 157 deflects sufficientlythat the ramped engagement feature 158 clears the inner surface of theshell 125 allowing for separation of the two portions 120 and 140. It isnoted here that the sloping surface of the ramped engagement feature 158together with the downward force from the release button 137 creates aseparation force such that when the ramped engagement feature 158 clearsthe bottom surface of the shell 125, the two portions 120 and 140 arebiased toward separation and thus a separate tensile force may not berequired to separate the two portions 120 and 140.

FIGS. 13-16 show a latch assembly 200 according to certain embodiments.In one embodiment, the latch assembly includes a female portion 220 anda male portion 240, which latch together to form a seam 270. Conduits260 and 280 similar to those shown in FIGS. 1 and 3 are included, butare not shown for clarity.

FIGS. 17-20 show the female portion 220 of the embodiment shown in FIGS.13-16 in greater detail. The female portion 220 of the latch assembly200 is shown to have a proximal end 221 and a distal end 222. The femaleportion 220 is also shown to include a shell 225 and a connectionopening 235 with an associated raised rib 238.

In the present embodiment, the shell 225 of the female portion 220 has alongitudinal axis 223. The shell 225 is generally hollow with a varyingoblong shaped cross-section when viewed along the longitudinal axis 223.The cross-section varies from relatively narrow at its proximal end 221to relatively broad at its distal end 222. The shell includes anopening/connection for a conduit at its proximal end. The shell furtherincludes an abutment face 229 at the distal end 222, following theperimeter contour of the shell 225. Those skilled in the art willunderstand and appreciate that virtually any shaped cross-section can beused including, but not limited to, circular, square, and rectangularshapes.

In the present embodiment, the connection opening 235 of the femaleportion 220 is best shown in FIGS. 17 and 20 and is shaped to receive arelease button 257 of the male portion 240, described below. It is notedthat the present embodiment includes two connection openings 235 locatedon opposing surfaces of the female portion 220. For purpose ofdescription, only one of the connection openings 235 is describedherein. The connection opening 235 has a proximal end 231 and a distalend 232, where the proximal end 231 is near the proximal end 221 of thefemale portion 220 and the distal end 232 is near the distal end 222 ofthe female portion 220. The connection opening 235 is surrounded by araised rib 238 with a side face 239 defining the outer perimeter of theconnection opening 235. The connection opening is narrower at itsproximal end 231 than at its distal end 232 and is shaped with smoothcorners.

FIGS. 21-24 show the male portion 240 of the embodiment shown in FIGS.13-16 in greater detail. The male portion 240 of the latch assembly 200is shown to have a proximal end 241 and a distal end 242. The maleportion 240 is also shown to include a shell 245 and a connectionassembly 255.

In the present embodiment, the shell 245 has a longitudinal axis 243.The shell 245 is generally hollow with a varying oblong shapedcross-section when viewed along the longitudinal axis 243. The outercontour of the shell 245 at its distal end matches the outer contour ofthe shell 225 at its distal end 222. As with the latch assembly 100,this provides for a smooth surface transition between the female 220 andmale 240 portions of the latch assembly 200. The cross-section of theshell 245 varies from relatively narrow at its proximal end 241 torelatively broad at its distal end. The shell 245 includes an exitopening/connection for a conduit at the proximal end 241. Those skilledin the art will understand and appreciate that virtually any shapedcross-section can be used including, but not limited to circular,square, and rectangular shapes. Those skilled in the art will alsounderstand and appreciate that a smooth transition may not always benecessary or desired and thus the outer contour of the shell 225 and theshell 245 would not need to match.

In the present embodiment, the connection assembly 255 of the maleportion 240 is situated at the distal end of the male portion 240 and isseparated from the shell 245 by an abutment face 249. The connectionassembly 255 comprises a necked-down section of the shell 245 such thatthe outer contour of the connection assembly 255 substantially matchesthe inner contour of the shell 225 of the female portion 220. Thisprovides for a mating relationship between the female portion 220 andthe male portion 240 where the connection assembly 255 extends withinthe shell 225.

In contrast to the embodiment shown in FIGS. 1-12, the connectionassembly 255 extends into the female portion 220 further than theconnection assembly 155 extends into the female portion 120. In thepresent embodiment, the connection assembly 255 extends substantially asfar as the proximal end 231 of the connection opening 235 of the femaleportion 220 when connected. The connection assembly 255 has a proximalend 251 and a distal end 252, where the proximal end 251 is adjacent theabutment face 249 and the distal end 252 extends to the distal end 242of the male portion 240.

The connection assembly 255 further comprises a release button 257supported near the distal end 252. It is noted that the connectionassembly 255 includes two release buttons 257 located on opposingsurfaces of the connection assembly 255. For purposes of description,only one of the release buttons 257 is described herein. The releasebutton 257 has a shape substantially matching that of the connectionopening 235 and a surface contour substantially matching that of theshell 225 of the female portion 220. Thus, the release button 257 israised above the necked-down surface of the connection assembly 255 soas to match the contour of the shell 225. The release button 257 extendsproximally from the distal end 252 of the connection assembly 255 and isseparated from the connection assembly 255 by a molded-in slot 256. Therelease button 257 has a proximal end 253 and a distal end 254, wherethe proximal end 253 is near the proximal end 251 of the connectionassembly 255 and the distal end 254 is near the distal end 252 of theconnection assembly 255.

In the present embodiment, the molded-in slot 256 surrounds the releasebutton 257 on three sides creating the cantilevered condition andcausing the release button 257 to have a peninsula-like shape matchingthat of the connection opening 235. The molded-in slot 256 surrounds therelease button 257 on the proximal end 253 and two sides generallyoriented parallel to the longitudinal axis 243.

As best shown in FIGS. 22 and 23, the release button 257 slopesgradually outward, relative to the internal space defined by the shell245, as the button extends from its distal end 254 toward its proximalend 253. Thus, when an object resistant to deflection slides along thesurface of the release button 257 from its distal end 254 to itsproximal end 253, the object will cause the release button 257 to flexinto the inner volume of the male portion 240 due to its cantileveredcondition and slope.

As best shown in FIG. 23, a latching face 259 is provided and is definedas the generally vertical face along the proximal end 253 of the releasebutton 257. The latching face 259 is shown opposing the abutment face249 and separated from the abutment face 249 by a portion of theconnection assembly 255 and the molded-in slot 256.

Having described the female portion 220 and the male portion 240 ingreat detail, reference is again made to FIGS. 13-16 showing the latchassembly 200. The female portion 220 and the male portion 240 may beconnected together in mating relationship. When the two portions areconnected, the abutment face 229 of the female portion 220 abuts againstthe abutment face 249 of the male portion 240 creating a seam 270 andpreventing the two portions 220 and 240 from advancing any furthertowards one another.

Reference is now made to FIG. 15 for describing in greater detail thelatching nature of the connection between the female portion 220 and themale portion 240. As the distal ends 222 and 242 of the two portions 220and 240 are brought together in opposing fashion, the connectionassembly 255 of the male portion 240 is inserted into the female portion220. As this occurs, the inner surface of the shell 225 passes along thesurface of the release button 257 causing it to deflect into the innerportion of the male portion 240 and allowing the two portions 220 and240 to continue to advance towards each other until the abutment faces229 and 249 are in contact. As with latch assembly 100, the portion ofthe shell 225 between the connection opening 235 and the distal end 222is minimal providing only a narrow strip of material to press againstthe release button 257. However this strip is reinforced by the raisedrib 238 and also can rely to a certain extend on the tensile hoopstresses developed in the shell as the two portions are assembled. Asthe abutment faces 229 and 249 are brought into contact, the releasebutton 257 comes into alignment with the connection opening 235 allowingthe release button 257 to spring back into its non-deflected shape. Inso doing, the latching face 259 of release button 257 is brought intoabutting relationship with the side face 239 of the raise rib 238creating a latched condition in which the two portions 220 and 240 arereleasably connected.

To release the female and male portions 220, 240 the release button 257may be pressed. In so doing, as can be seen in FIG. 15, the releasebutton 257 deflects sufficiently that the latching face 259 is no longerin abutting relationship with the side face 239 of the raise rib 238thus allowing for separation of the two portions 220 and 240.

FIGS. 25-28 show yet another latch assembly 300 according to certainembodiments. The latch assembly 300 resembles latch assembly 100 incertain respects and also includes some distinct differences asdiscussed below.

The latch assembly 300 includes a female portion 320 and a male portion340, which latch together to form a seam 370. Conduits 360 and 380similar to those shown in FIGS. 1 and 3 are also included. Each conduit360 and 380 includes a respective set of proximal ends 361 and 381respectively having hose barbs 362 and 382. Each conduit 360 and 380also includes a respective distal end 363 and 383, which are configuredto mate in a male/female mating arrangement.

While in one embodiment, hose barbs 362, 382 may be provided for joiningthe proximal ends 361, 381 to polymer tubing, in other embodiments, theproximal ends 361, 381 may be provided with other joining features, suchas threads, flanges, couplings, clamps, etc.

FIGS. 29-32 show the female portion 320 of the present embodiment. Thefemale portion 320 has a proximal end 321, distal end 322, a shell 325,and a connection assembly 335. The shell 325 has a longitudinal axis 323and a hollow, varying, oblong shaped cross-section. The shell 325further includes an abutment face 329 at the distal end 322. Theconnection assemblies 335 of the female portion 320 comprise a releasebutton 337, a molded-in slot 336, and a raised rib 338. The releasebutton 337 comprises a section of the shell 325 following the contour ofthe shell 325 and is separated from the shell 325 by a molded-in slot336 and a raise rib 338. The release button further has a proximal end331 and a distal end 332. The release button 337 is surrounded by themolded-in slot 336 on three sides, two generally parallel to thelongitudinal axis 323 and a third side along the release button's distalend 332. The molded-in slot 336 causes the release button 337 to have apeninsula-like shape and creates a cantilevered condition where therelease button 337 is narrower at its proximal end 331 than at itsdistal end 332. This cantilevered condition allows the distal end 332 ofthe release button 337 to flex into the interior space of the femaleportion 320 when pressed on from the outer side. The raised rib 338,like raised rib 138 projects outwardly relative to the inner space ofthe female portion 320 and has a side face 339 defining the outerperimeter of the molded-in slot 336.

In contrast to latch assembly 100, the release button also includes araised surface 337A and a raised pattern 337B. Also, the raised rib 338is shown not to completely surround the release button 337 and onlyoccurs on three sides of the release button. Moreover, the molded-inslot 336 does not extend as far around the release button so as tosurround it on a fourth side, but is limited to three sides.

Additional elements shown in FIGS. 29-32 include alignment recesses 326,a molded-in slot divider 336A and molded-in slot receiving areas 336B.The alignment recesses 326 occur on the inner surface of the shell 325and work to ensure alignment of the ramped engagement features 358 priorto full engagement of the male 340 and female 320 portions. Themolded-in slot divider 336A is a projection proximally extending fromthe shell 325 partially across the molded-in slot 336. This projectionbreaks up the molded-in slot 336 creating molded-in slot receiving areas336B for the ramped engagement features 358 to engage.

FIGS. 33-36 show the male portion 340 of the present embodiment. Themale portion 340 has a proximal end 341, a distal end 342, a shell 345,and a connection assembly 355. The shell 345 has a longitudinal axis 343and has a hollow, varying, oblong shaped cross-section. The outercontour of the shell 345 at its distal end matches the outer contour ofthe shell 325 at its distal end 322. The connection assembly 355 issituated at the distal end 342 and is separated from the shell 345 by anabutment face 349. The connection assembly 355 comprises a necked-downsection of the shell 345. The outer contour of the connection assembly355 substantially matches the inner contour of the shell 325 of thefemale portion 320 at its distal end 322 providing for a matingrelationship. The connection assembly 355 further comprises acantilevered region 357 and a ramped engagement feature 358. In thepresent embodiment, the connection assembly 355 includes fourcantilevered regions 357. However, in other embodiments, there may agreater or lesser number of cantilevered regions 357. For purposes ofdescription, only one of the cantilevered regions 357 is describedherein.

The cantilevered region 357 is distinct from the cantilevered region 157of latch assembly 100 in several respects. First, the cantileveredregion is further necked down from the connection assembly. Second, thecantilevered region 357 is fixed to the connection assembly 355 at thecantilevered region's proximal end 351 rather than its distal end 352.Third, the ramped engagement feature 358 is located at the cantileveredregion's distal end 352 rather than its proximal end 351. However, theorientation of the ramped engagement feature 358 has remained the samein that the surface of the ramped engagement feature 358 slopesoutwardly relative to the inner volume of the male portion 340 as thesurface extends from its distal end to its proximal end. An additionaldistinction of the latch assembly 300 from latch assembly 100 is thatthe surface of the ramped engagement feature 358 is convex.

The male portion 340 also includes raised surface features 347 on theshell 345. In addition, the connection assembly 355 includes cutawayrecesses 356A on the inner surface which aid in minimizing the depth ofthe assembly while still accommodating the conduit. The connectionassembly 355 also includes slits 356B along the sides of the connectionassembly 355 separating two of the four cantilevered regions 357. Theseslits allow for easier deflection of the cantilevered region 357.Further to this idea of easier deflection of the cantilevered region357, FIG. 29 shows a more substantial strip of material remainingbetween the molded-in slot 336 and the distal end 322 of the femaleportion 320. This causes this strip to be stiffer than that shown, forexample, in FIG. 8 and adds to the ability of the device to causedeflection of the cantilevered region 357.

Also shown is a latching face 359 of the ramped engagement feature 358defined as the generally vertical face beyond the end of the rampedportion of the ramped engagement feature 358. The latching face 359 isshown opposing the abutment face 349 and separated from the abutmentface 349 by a length of the cantilevered region 357 and a portion of theconnection assembly 355. The ramped portion of the ramped engagementfeature 358 and the latching face 359 come together at a point or ridge358A. The ridge 358A is adapted to fit into the molded-in slot receivingareas 336B.

As with latch assemblies 100 and 200, the female portion 320 and themale portion 340 may be connected together in mating relationship. Asshown in FIGS. 25-28, when the two portions are connected, the abutmentface 329 of the female portion abuts against the abutment face 349 ofthe male portion creating a seam 370 and preventing the two portionsfrom advancing any further toward one another.

As the distal ends 322 and 342 of the two portions 320 and 340 arebrought together in opposing fashion, the ramped engagement features 358initially engage the alignment recesses 326. This initial contact aidsthe user in assuring that the two portions 320 and 340 are properlyaligned. As the two portions continue to advance, the sloping surface ofthe ramped engagement feature 358 causes the cantilevered regions 357 todeflect until the entire ramped engagement feature 358 passes within theinner surface of the shell 325. This allows for complete advancement ofthe female portion 320 and male portion 340 toward one another andbringing abutment face 329 into contact with abutment face 349,preventing further advancement. At the same time, the ramped engagementfeature 358 passes within the volume defined by the shell 325 and itencounters the molded-in slot receiving areas 336B. The ridge 358A ofthe ramped engagement feature 358 enters the molded-in slot receivingareas 336B allowing the cantilevered regions 357 to spring back intotheir non-deflected position. As this occurs, the latching face 359 ofthe ramped engagement feature 358 is brought into abutting relationshipwith the side face 339 of the raised rib 338 creating a latchedcondition in which the two portions 320 and 340 are releasablyconnected.

To release the female and male portions 320, 340 the release button 337may be pressed. In so doing, the release button 337 engages the rampedengagement feature 358 and both the release button 337 and thecantilevered region 357 deflect into the inner volume of theirassociated shells. When the release button 337 is pressed withsufficient force, the cantilevered region 357 deflects sufficiently thatthe ramped engagement feature 358 clears the inner surface of the shell325 allowing for separation of the two portions 320 and 340. As withlatch assembly 100, the sloping surface of the ramped engagement feature358 together with the downward force from the release button 337 createsa separation force such that when the ramped engagement feature 358clears the bottom surface of the shell 325, the two portions 320 and 340are biased toward separation and thus a separate tensile force may notbe required to separate the two portions 320 and 340.

FIGS. 37-40 show yet another embodiment of a female portion 420 of alatch assembly. The female portion 420 of the latch assembly shown inFIGS. 37-40 resembles the female portion 320 of latch assembly 300 inmost respects and a corresponding male portion 440 is not shown. Assuch, the female portion 420 will be described as interacting with maleportion 340.

As best shown in FIGS. 37 and 39, the inside surface of the releasebutton 437 includes two raised protuberances 437A. These raisedprotuberances may be positioned in a corresponding location to theramped engagement features 358 of the male portion 340. When releasingthe male and female portions 340 and 420, as with latch assembly 300 and100, the sloping surface of the ramped engagement feature 358 togetherwith the downward force from the release button 437 creates a separationforce such that when the ramped engagement feature 358 clears the bottomsurface of the shell 425, the two portions 420 and 340 are biased towardseparation. Thus a separate tensile force may not be required toseparate the two portions 420 and 340. In addition to that provided bylatch assemblies 100 and 300, however, the raised protuberances 437A ofthe female portion 420 further act to pinch the cantilevered regions 357together. This pinching force further acts on the ramped engagementfeather 358 to further bias the male portion 340 and female portion 420toward separation and further causing a spring-out motion between themale and female portions.

Those skilled in the art will understand and appreciate that severalmodifications and variations exist within the scope of the presentinvention. For example, the hollow cross sections described could bepartially solid while still accommodating a conduit and allowing for thedeflection of the release buttons and other cantilevered actions. Thecross section could, for example, actually form a conduit by providing agenerally solid cross-section while providing a conduit passing throughthe cross section. As an additional example of a variation within thescope of the invention, the embodiments shown include two opposingrelease buttons while this could be limited to one release button orseveral release buttons could be provided. The molded-in slot could becut out after molding or it could be a weakened area (e.g. thinnermaterial). Alternatively, the whole surface of the shell could beflexibly deflectable and the slot could be omitted. Additionally, ratherthan elastically flexible cantilevered release buttons, the buttonscould be hinged and spring loaded. Various shaped buttons could beprovided to accommodate ergonomics or function of the device and wouldnot have to match the contour of the shell. The release buttons havebeen described with four sides, but could be any shape and have varioussides where one or two or even several are connected and the others arenot to provide a cantilevered effect. As another example, the rampedengagement feature could be limited to a projection adapted to fit intoa recess on the inside of a shell and various shapes of the projectioncould be included and matched to a recess formed in the shell.

The advantages of the latch assembly as described above include itsability to be quickly and easily engaged and released. The releasebuttons and engagement features of the described device may allow forefficient splicing of conduits by advancing the male and female portionstoward one another and efficient release by pressing the release button.This is in contrast to threaded connections requiring alignment and timeconsuming twisting of the connections which often results in twisting ofthe conduits and tangling of the conduits.

Another advantage of the latch assembly described is the secureconnection provided. In light of the efficiency discussed above relatingto the ease with which the assembly can be spliced, the secureconnection provided remains consistent with that necessary to avoidunwanted failure of a connection.

Another advantage of the latch assembly is the effectiveness of theconnection provided. Also in light of the efficiency discussed aboverelating to the ease of use of the assembly, the latching nature of thedevice also provides for an effective connection in that the conduitsare connected so as to minimize or eliminate unwanted leaks or escape ofmatter carried in the conduit.
